Appl. No.:

10/922630

Jeffrey M. Gabelmann - Boerne TX, US
J. Stephen Kattner - San Antonio TX, US

International Classification:

G01V 3/00

US Classification:

3408546, 343893, 166 66, 702 17, 702 5

Abstract:

This invention is an ultra-low frequency electromagnetic telemetry receiver which fuses multiple input receive sources to synthesize a decodable message packet from a noise corrupted telemetry message string. Each block of telemetry data to be sent to the surface receiver from a borehole tool is digitally encoded into a data packet prior to transmission. The data packet is modulated onto the ULF EM carrier wave and transmitted from the borehole to the surface and then are simultaneously detected by multiple receive sensors disbursed within the rig environment. The receive sensors include, but are not limited to, electric field and magnetic field sensors. The spacing of the surface receive elements is such that noise generators are unequally coupled to each receive element due to proximity and/or noise generator type (i. e. electric or magnetic field generators). The receiver utilizes a suite of decision metrics to reconstruct the original, non noise-corrupted data packet from the observation matrix via the estimation of individual data frames.

International Classification:

A23L 1015

US Classification:

426423

Abstract:

Polyol polyesters are purified by a process comprising bleaching with a specific silica gel and/or heat treatment and removal of volatile products by steam deodorization. Any steam deodorization is at reduced temperatures or in admixture with triglycerides to minimize thermal degradation of the polyol polyesters.

Abstract:

A method for detecting an diagnosing faults in printed circuit boards. Emissivity data and thermal image data of the various components of the board are obtained. The emissivity data is used to correct the thermal image data. The corrected data is converted to device space data, which is then input to a previously trained neural network. The output of the neural network indicates the location of the fault. The method includes an improved method for obtaining an emissivity map and a method for providing suitable neural network input.
